Positive at 15 weeks pp

My daughter is only about 14w4d old and I just toke a pregnancy test and got a positive. My boyfriend and I are not in a good spot right now. We’ve been fighting like crazy and are at each other’s necks all the time. We both want to make it work but since the baby has been born it’s been so hard. Now I’m pregnant again and he leaves for army officer training over the summer for 6 months. I have no idea what to do. I told him I don’t think I should keep the baby since we’re not in the right spot financially for another child but he told me not to make any rash decisions. I know it’s my choice but I have no idea what to do. I’m 20 and he’s 22. I’m a SAHM living with my brother and he’s in college living on campus. I need advice please.

Edit 1: I’m going to talk to him more when he gets home from work. I’ve been dealing with what seems with symptoms of PPD and have not been feeling well lately. Hopefully it doesn’t turn into a huge argument.
